Title: Air flow rate measuring device
Inventor: TAKAHASHI MINORU
IPC: F02D45/00
Filed: 1992-08-27
Abstract: PURPOSE:To obtain a heating type air flow rate meter which is improved in characteristic and accuracy without degrading the response capability by providing a part of bobbin inner diameter with a plurality of continuous concave parts in inner diameter axis direction. CONSTITUTION:The air sucked in a body 1 is separated to a main air path 3 and a bypass path 4. To a heating resister 5 arranged in the path 4, a voltage for heating to a constant temperature is impressed. For controlling the temperature constant, current is needed to increase according as the flow rate. This air flow rate meter measures flow by utilizing the output voltage characteristic. As an information source for air density, the air temperature is corrected for use with a temperature sensing resister 6. Therefore, by providing a part of the inner diameter of an alumina bobbin 11 with a plurality of concave parts 12, the heat capacity of the bobbin 11 itself is suppressed small maintaining a metal lead 13 nearly in the center of the bobbin 11. By this, the output characteristics scattering of air flow rate without degrading the response capability and an air flow rate measuring device with drastically improved accuracy is obtained.

Title: High frequency heating mandrel and manufacture of crosslinked rubber hose using the same
Inventor: MIO KOTARO
IPC: B29C35/10
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To enable the industrial continuous production of a crosslinked rubber hose by providing a surface layer composed of an org. polymer on a conductive layer containing a specific amt. of a metal element having a specific aspect ratio. SOLUTION: A conductive layer 3 is a layer heated by high-frequency waves and, as a conductive material, a metal element of which the aspect ratio is at least 100 is used. A metal element with an aspect ratio of below 100, for example, a usual powder is low in the gathering density of the metal element in the conductive layer and can not effectively heat a mandrel. Since the mandrel can be heated to high temp. by high frequency heating as mentioned above, the crosslinkable rubber subjected to extrusion molding on the mandrel can be heated from its inner surface. Therefore, a crosslinking time of rubber can be shortened to a large extent. Since the surface layer of the mandrel is composed of an org. polymer, the mandrel is easily extracted from a crosslinked rubber layer after a rubber crosslinking process.

Abstract: PURPOSE:To provide a variable resistor, the connecting sections of which are improved in reliability, by increasing the connection strength between electrodes and lead terminals. CONSTITUTION:This variable resistor, in which lead terminals 1 are respectively connected to current collecting electrode bodies 3 formed on an insulating aluminum substrate 2 by thermocompression bonding, has holes 1a near the connecting sections of the terminals 1 at parts covered with a resin case 5 formed by insert molding. Since the holes 1a are provided near the connecting sections of the terminals 1 with the electrode bodies 3, the strength of lead terminal connecting sections 1b can be improved and, after the resin case is molded, the bodies 3 and terminals 1 are hardly disconnected from each other at their connecting sections even when the terminals are pulled at the time of bending leads, since the terminals 1 are sufficiently fixed by the resin of the case 5 which deeply gets into the holes 1a at the time of molding the case 5. Therefore, the reliability of the connecting sections can be improved.

Title: Visco-elasticity measuring device
Inventor: MATSUSHITA KENICHI
IPC: G01N19/00
Filed: 1988-09-13
Abstract: PURPOSE:To obtain data of waveforms of attenuation correctly and stably even for a hard sample by adding to said sample and external force having a frequency approximately half the resonance frequency of said sample as an initial external force. CONSTITUTION:Driving coils 22A, 22B are used so as to apply an initial twist to an inertial body 15. The driving coils 22A, 22B are supplied with a driving signal having a frequency approximately half the resonance frequency, thereby generating a suction force having the resonance frequency of a sample 11. The suction force becomes an initial external force. If the driving signal is supplied a short time, the sample 1 is instantaneously accompanied with the mechanical resonance. Accordingly, the sample 11 continues vibrating with maximum stable amplitude. The driving signal is stopped after the sample fully vibrates at a resonance point. Then, a stable waveform of free attenuation without confusing vibrations such as longitudinal or transverse vibrations is obtained. Even when the sample is a hard one, the vibration of the sample receives more kind of inducement from the resonance, so that the supplying energy can be small, with the driving time restricted short.
